Specifically, the first, second, third, and fourth cameras 111, 112, 113, and 114 may provide the first, second, third, and fourth image data 201, 202, 203, and 204 as shown in FIG. 3 to the controller 140.

Each of the first, second, third, and fourth cameras 111, 112, 113, and 114 may include, for example, a fisheye lens in order to expand a photographable field of view. Accordingly, the first, second, third, and fourth image data 201, 202, 203 and 204 photographed by the first, second, third, and fourth cameras 111, 112, 113, and 114, respectively may be a fisheye-view as shown in FIG. 3 . For example, in the first, second, third, and fourth image data 201, 202, 203, and 204, the height of the center portion of the image and the height of the left and right edge portions of the image may be different from each other.

The controller 140 may correct the fisheye-view image data 201, 202, 203, and 204 into top-view image data. For example, the controller 140 may correct the fisheye-view image data 201, 202, 203, and 204 to the top-view data 211, 212, 213, and 214 using a de-warping algorithm.

As shown in FIG. 4 , the controller 140 may correct the first, second, third, and fourth image data 201, 202, 203, and 204 to the first, second, third, and fourth top-view data 211, 212, 213, and 214.

The controller 140 may generate around-view data 220 around the vehicle 1 as shown in FIG. 5 by combining a plurality of top-view data 211, 212, 213, 214.

The controller 140 may correct the first, second, third, and fourth top-view data 211, 212, 213, and 214.

For example, the controller 140 cuts the first, second, third, and fourth top-view data 211, 212, 213, and 214 into a substantially trapezoidal shape and then may combine the cut top-view data 211, 212, 213, and 214 as shown in FIG. 5 . As shown in FIG. 5 , the first top-view data 211 and the second top-view data 212 are cut so that the angle between the base and the hypotenuse (hereinafter referred to as “the angle of the hypotenuse”) is 34 degrees. The third top-view data 213 and the fourth top-view data 214 may be cut so that the angle between the base and the hypotenuse (hereinafter, referred to as “the angle of the hypotenuse”) is 56 degrees.

The controller 140 may combine the cut top-view data 211, 212, 213, and 214 so that hypotenuses of the cut top-view data 211, 212, 213, and 214 face each other. The around-view data 220 may be generated by combining the cut top-view data 211, 212, 213, and 214.

In this case, the around-view data 220 may include a plurality of boundaries 221, 222, 223, and 224 in which the cut top-view data 211, 212, 213, and 214 are combined. The plurality of boundaries 221, 222, 223, and 224 may include a first boundary 221 in which the first top-view data 211 and the third top-view data 213 are combined, a second boundary 222 in which the first top-view data 211 and the fourth top-view data 214 are combined, a third boundary 223 in which the second top-view data 212 and the third top-view data 213 are combined, and a fourth boundary 224 in which the second top-view data 212 and the fourth top-view data 214 are combined. The angle between the longitudinal axis of the vehicle 1 (the axis extending in the front-rear direction of the vehicle) and the first boundary 221 (hereinafter referred to as “the angle of the first boundary”) and an angle between the longitudinal axis of the vehicle 1 and the second boundary 222 (hereinafter, referred to as an “angle of the second boundary”) may be a first reference angle (e.g., 56 degrees). In addition, the angle between the longitudinal axis of the vehicle 1 and the third boundary 223 (hereinafter referred to as “the angle of the third boundary”) and the angle between the longitudinal axis of the vehicle 1 and the fourth boundary 224 (hereinafter referred to as “angle of the fourth boundary”) may also be the first reference angle (e.g., 56 degrees).

The controller 140 may transmit the around-view data 220 to the display 10 so that the around-view image is displayed on the display 10.

As described above, when the first, second, third, and fourth top-view data 211, 212, 213, and 214 are corrected to have a hypotenuse of a predetermined angle, the obstacle 2 may not be displayed properly.

For example, as shown in FIG. 5 , when the obstacle 2 is located on the front left side of the vehicle 1, an image information about the obstacle 2 may be removed by correction (cutting) of the first top-view data 211 of the vehicle 1 and correction (cutting) of the third top-view data 213. In other words, the obstacle 2 may not be displayed in the around-view data (220).

To prevent obstacle 2 from not being displayed in around-view data(220) like this, the controller 140 may correct the first, second, third, and fourth top-view data 211, 212, 213, and 214 based on whether an obstacle is located around the vehicle 1 and the location of the obstacle.

When an obstacle is located around the vehicle 1, the controller 140 may correct (cut) the image data so that the area occupied by image data (top-view data) indicating the area where the obstacle is located is expanded.

For example, if an obstacle is not located around the vehicle 1 as shown in FIG. 6A, the controller 140 may correct the top-view data 211, 212, 213, and 214 to have a hypotenuse of a predetermined reference angle (e.g., 34 degrees or 56 degrees).

As another example, as shown in FIG. 6B, if the obstacle 2 is located in the rear of the vehicle 1, the controller 140 may correct the top-view data 211, 212, 213, and 214 so that the second top-view image representing the rear of the vehicle 1 in the around-view image is expanded. The controller 140 may correct the second top-view data 212 so that the angle of the hypotenuse of the second top-view image is changed (eg, changed to 10 degrees). Also, the controller 140 may correct the third top-view data 213 and the fourth top-view data 214 so that the angle of the hypotenuse of the third top-view image and the fourth top-view image is changed (eg, changed to 80 degrees). In the around-view image, the angle of the third boundary 223 and the angle of the fourth boundary 224 may be changed to a second reference angle (eg, 80 degrees). In other words, the third boundary 223 may be inclined toward the left side of the vehicle 1, and the fourth boundary 224 may be inclined toward the right side of the vehicle 1. By such a structure, the area of the image photographed by the second camera 112 installed at the rear of the vehicle 1 in the around-view image can be expanded, and the obstacle 2 located at the rear of the vehicle 1 can be displayed on the around-view image without distortion.

As another example, as shown in FIG. 6C, if the obstacle 2 is located on the right side of the vehicle 1, the controller 140 may correct the top-view data 211, 212, 213, and 214 so that the fourth top-view image representing the right side of the vehicle 1 in the around-view image is expanded. The controller 140 may correct the fourth top-view data 214 so that the angle of the hypotenuse of the fourth top-view image is changed (e.g., changed to 10 degrees). Also, the controller 140 may correct the first top-view data 211 and the second top-view data 212 so that the hypotenuse angles of the first top-view image and the second top-view image are changed (e.g., changed to 80 degrees). In the around-view image, the angle of the second boundary 222 and the angle of the fourth boundary 224 may be changed to a third reference angle (e.g., 10 degrees). In other words, the second boundary 222 may be inclined toward the front of the vehicle 1, and the fourth boundary 224 may be inclined toward the rear of the vehicle 1. By such a structure, the area of the image photographed by the fourth camera 114 installed on the right side of the vehicle 1 in the around-view image can be expanded, and the obstacle 2 located on the right side of the vehicle 1 can be displayed on the around-view image without distortion.

As another example, as shown in FIG. 6D, if the obstacle 2 is located on the rear and right side of the vehicle 1, the controller 140 may correct the top-view data so that the second top-view image representing the rear of the vehicle 1 and the fourth top-view image representing the right side of the vehicle 1 are expanded in the around-view image. In the around-view image, the angle of the second boundary 222 may be changed to a third reference angle (e.g., 10 degrees), and the angle of the third boundary 223 may be changed to a second reference angle (e.g., 80 degrees). The angle of the fourth boundary 224 in which the second top-view data 212 and the fourth top-view data 214 are in contact may maintain a first reference angle (e.g., 56 degrees). In other words, the second boundary 222 may be inclined toward the front of the vehicle 1, and the third boundary 223 may be inclined toward the right side of the vehicle 1. By such a structure, the area of the image photographed by the second camera 112 and the fourth camera 114 installed on the right side of the vehicle 1 in the around-view image can be expanded, and the obstacles 2 located on the rear and right sides of the vehicle 1 can be displayed on the around-view image without distortion.

As described above, the controller 140 may generate around-view data 220 based on the detected obstacle, and transmit the around-view data 220 to the display 10 to display the around-view image.

Various embodiments of generating around-view data 220 are described below.

FIGS. 7A and 7B illustrate an example of around-view data generated by a driver assistance apparatus according to an embodiment while a vehicle is parked and while driving.

If vehicle 1 is parked or the driving speed is less than the reference speed, the driver assistance apparatus 100 may generate around-view data 220 by combining image data photographed by the first, second, third, and fourth cameras 111, 112, 113, and 114. The driver assistance apparatus 100 may set angles of the first, second, third, and fourth boundaries 221, 222, 223, and 224 of the around-view data 220 as a first reference angle (e.g., 56 degrees) as shown in FIG. 7A.

If the driving speed of vehicle 1 is greater than or equal to the reference speed, the driver assistance apparatus 100 may set the angles of the first, second, third, and fourth boundaries 221, 222, 223, and 224 of the around-view data 220 as a third reference angle (e.g., 10 degrees) as shown in FIG. 7B.

When the door of the vehicle 1 is opened while the vehicle 1 is parked, the driver assistance apparatus 100 may set the angles of the first, second, third, and fourth boundaries 221, 222, 223, and 224 as second reference angle (e.g., 80 degrees).

In addition, if the trunk gate of the vehicle 1 is opened while the vehicle 1 is parked, the driver assistance apparatus 100 may set the angles of the first boundary 221 and the second boundary 222 in front of the vehicle 1 as a second reference angle (e.g., 80 degrees) and set the angles of the third boundary 223 and the fourth boundary 224 at the rear of the vehicle 1 as a third reference angle (e.g., 10 degrees).

FIGS. 8A and 8B illustrate an example of around-view data generated by a driver assistance apparatus according to an embodiment while a vehicle is moving. FIGS. 9A, 9B, and 9C illustrate an example of around-view data generated by a driver assistance apparatus according to an embodiment while a vehicle is moving.

While the vehicle 1 is moving backward, the driver assistance apparatus 100 may detect an obstacle 2 located at the right rear side of the vehicle 1 based on detection data of ultrasound sensors 121, 122, 123, and 124.

The driver assistance apparatus 100 may generate around-view data 220 such that a region of the right image photographed by the fourth camera 114 in the around-view image is expanded based on the detection of the obstacle 2 located in the rear right of the vehicle 1. For example, as shown in FIG. 8A, the driver assistance apparatus 100 maintains the angle of the first boundary 221, the angle of the second boundary 222, and the angle of the third boundary 223 of the around-view data 220 as a first reference angle (e.g., 56 degrees) and may change the angle of the fourth boundary 224, which is a boundary of the right and rear sides of the vehicle 1, to a third reference angle (e.g., 10 degrees).

While the vehicle 1 is moving backward, the driver assistance apparatus 100 may detect an obstacle 2 located at the rear of the vehicle 1 based on detection data of ultrasound sensors 121, 122, 123, and 124.

The driver assistance apparatus 100 may generate around-view data 220 such that a region of the rear image photographed by the second camera 112 in the around-view image is expanded based on the detection of the obstacle 2 located at the rear of the vehicle 1. For example, as shown in FIG. 8B, the driver assistance apparatus 100 maintains the angle of the first boundary 221 and the angle of the second boundary 222 of the around-view data 220 as a first reference angle (e.g., 56 degrees) and may change the angle of the third boundary 223 and the angle of the fourth boundary 224 of the rear of the vehicle 1 to a second reference angle (e.g., 80 degrees).

In addition, while the vehicle 1 is moving backward, the driver assistance apparatus 100 may generate around-view data 220 such that the area of the rear image in the around-view image is expanded based on the distance between the vehicle 1 and the obstacle 2.

For example, based on the obstacle 2 not being detected, as shown in FIG. 9A, the driver assistance apparatus 100 may correct the image data so that angles of the first, second, third, and fourth boundaries 221, 222, 223, and 224 of the around-view data 220 become a first reference angle (e.g., 56 degrees).

Based on a determination that the obstacle 2 is detected by the movement of the vehicle 1 and the distance to the obstacle 2 is greater than or equal to the reference distance, as shown in FIG. 9B, the driver assistance apparatus 100 may still correct the image data so that the angles of the first, second, third, and fourth boundaries 221, 222, 223, and 224 of the around-view data 220 become the first reference angle (e.g., 56 degrees).

Based on a determination that the obstacle 2 is detected by the movement of the vehicle 1 and the distance to the obstacle 2 is less than the reference distance, as shown in FIG. 9C, the driver assistance apparatus 100 may correct the image data so that the angles of the third and fourth boundaries 223 and 224 of the around-view data 220 become the second reference angle (e.g., 80 degrees).

The driver assistance apparatus 100 may change the angle of the fourth boundary 224 of the around-view data 220 to a third reference angle (e.g., 10 degrees) as shown in FIG. 10A based on detecting the obstacle 2 moving from the right rear side of the vehicle 1.

The driver assistance apparatus 100 may detect an obstacle 2 moving from the rear of the vehicle 1 based on detection data of the ultrasound sensors 121, 122, 123, and 124.

Also, while the obstacle 2 is moving toward the vehicle 1, the driver assistance apparatus 100 may generate around-view data 220 such that the area of the rear image in the around-view image is expanded based on the distance between the vehicle 1 and the obstacle 2.

For example, based on the obstacle 2 not being detected, as shown in FIG. 11A, the driver assistance apparatus 100 may correct the image data so that angles of the first, second, third, and fourth boundaries 221, 222, 223, and 224 of the around-view data 220 become a first reference angle (e.g., 56 degrees).

Based on a determination that the obstacle 2 is detected by the movement of the obstacle 2 and the distance to the obstacle 2 is greater than or equal to the reference distance, as shown in FIG. 11B, the driver assistance apparatus 100 may still correct the image data so that the angles of the first, second, third, and fourth boundaries 221, 222, 223, and 224 of the around-view data 220 become the first reference angle (e.g., 56 degrees).

FIG. 17 illustrates an example of changing boundaries of around-view data of a driver assistance apparatus according to an embodiment.

The driver assistance apparatus 100 may change the angle of the boundaries 221, 222, 223, and 224 combining the top-view data 211, 212, 213, and 214 to generate the around-view data 220.
